After learning all about the plants, animals and Aboriginal history of Ku-ring-gai Chase National Park at Kalkari Discovery Centre, head along the moderately difficult Birrawanna walking track. The kids will love putting their newfound knowledge into practice. A great nature adventure on a family day trip, historic Birrawanna walking track leads to Bobbin Head, where you can stop for a waterfront picnic or grab a tasty lunch at Bobbin Inn Café.

Skirting the emu enclosure, the medium difficulty track passes through woodlands of scribbly gum and red bloodwood to join a historic track of open forests before reaching Bobbin Head. Be sure to look for the vibrant red waratah.

On the way back up, stop for a breather and check out the lovely views over Cockle Creek and Cowan Water. You might see a brown hawk or nankeen kestrel circling above, looking for lizards and insects.
